Patented Jan. 15, 1935 UNITED stares ATEN FFICE The subject matter ofthis inventionis generally concerned with gripping and extractinginstruments and more particularly. is directed to a manuallycontrolleddouble wing self releasing tweezer for extracting hair.

. In the performance of tweezers of ,thecharacter referred to, it isvery desirable to maintain sufficient pressure on the hair gripping andextracting jaws during their rearward extracting stroke upon themanipulation of ,the arms or wings of the tweezers. In practicehoweverit has been found that the pressure of the gripping jaws-on ahair to be extracted was practically at a maximum only at the beginning"of their rearward stroke. After the beginning or during therearwardstroke of the jaws; the holding pressure on the hair gripping surfacesthereof lessened with the result that the initial'grip on the hair to beextracted became-correspondingly less as the extracting strokeprogressed such that although the jaws were movingrearwardly jtoextractthe hair, the jaws failed to effectively hold and'grip the hair. Withthis difiiculty experienced, the hair to which the tweezer was appliedwould not be extracted dueto the ineffective gripping as a result ofslippageof the tweezer jaws over the hair. It is therefore a particularobject of the invention to provide an improved tweezer or manuallyactuated instru 'ment'in which the jaws are maintained-at an efiectivegripping pressure throughout their rearward and complete extractingstroke 'to prevent slippage of jaws over the hair to which the tweezeris applied."

16 but includingsprings interposed between the, jaws-and wings toprovide automaticsidepressure to the jaws'on the extracting-stroke.

The gripping and extracting. deviceor tweezer instrument according to a'specific embodiment of the invention includes a pair of elongated jaws,the lower operating faces at one-end thereof may be'iiattened'and/orcorrugated to form gripping faces to effectively hold the hair to beextracted; and the other end. of the jawsare so provided with correlatedrecesses, projections and shoulders and positioned inside of :acylindrical guide that an, effective pivotal connection is formedtherebetween. symmetrically attached to the sides of the jaws by pivotedlinks and in slotser sockets in the upper part of the cylindrical guideby elongated recessed and grooved respective spring.

lindrical guideis positioned a helicoidal spring on which is seated acylindrical plug or retainer which cooperates with the recesses of thelateral disposed flanges for locking them in position and with the jawsto normally hold them spread apart.

In one embodiment, side pressure is normally exerted on the jaws of thetweezer by a pair of laterally extending springs having their inner endspassing through a perforation in the cylindrical guide and bearingagainst adjacent upper portion of the jaws while the outer portions ofthe spring are suitably mounted on the inner faces of the wings of thetweezer.

In another embodiment of the invention provision has been made forregulating the pressure with the arms of the tweezer for eitheradjustably increasing or lessening the tension of a i In carrying theinvention into effect the pressure springs interconnecting the arms andjaws of the tweezers, provide a certainforce against the sides of thejaws to effectively hold the hair gripping faces against the hair to beextracted on the extracting stroke of the jaws and the pressure springsmay be interconnected between the arms and jaws of the tweezer-as to besubtracting stroke of the'jaws in utilizing an adjustable and rotatableguide sleeve in which the pivotal joint of the jaws are housed, whichsleeve upon rotation controls the elevation of an adjustable memberconnected to one of the jaws to limit their rearward movement and theadjustable member cooperates with suitable spring means whereby varyingdegrees ofpressure may be transmitted to the jaws for their separation.

Referring now to the drawings, the tweezer instrument as shown inthe-several views is provided with a pair of elongated substantiallysemi cylindrical jaws 10 and 11 having hair gripping and extractingfaces 12 and 13 whichqmay be suitably roughened, smoothed orcorrugatedand extend beyond thev respective rectilinear inner faces 14 and 15. Theother ends of the jaws are retained inside of the cylindrical sleeve orguide 16 and their contracting faces are so constituted as to form apivotal connection therebetween. In forming this pivotal connection, jaw10 is provided with a channel 17 to receive the elongated boss or ridge18 of the jaw 11.

Sides 19 of the channell? project beyond the rectilinear face 14 to forma shoulder 20 which cooperates with the shoulder 21 formed by thedepression 22 above face 15. The bottom face 23 of the cylindrical end24 of jaw 11 serves as a stop for the sloping end 25 of jaw 10.

drical plug 29 and the latter locks the wings 3'3 .in position in thesockets 31 and prevents disengagement of the flanges 32 from the squaredportion of the guide or sleeve.

The overhanging lips or edges 36 of the sockets 31 cooperate with thetransversely disposed grooves 37 on the upper part of the flanges 32whereby the upper portion of the arms or wings are retained in thesockets and consequently lateral slippage of the arms 33 is prevented.

The outer faces of the wings33 are desirably embellished or decorated asis also the outside of the guide 16 and the lower portions of the wingsare suitably flattened or ridged to form grips in any appropriatemanner. i

The inner faces of wings 33 and the outer faces of jaws 10 and 11 areprovided with ears 38 and 39 respectively in which (see also Fig. 4) arepress fitted the pivotfpins 40, the ends 41' of which are of reduceddiameter and receive the sides of the U shaped channellink 42, thechannel portion facing downwardly and forwardly.

According to the invention, the upper closed face of the link 42 uponcollapsing of the tweezer instrument is stopped by the extension 44 ofthe projecting ears 38 (see Fig. 2).

In expanded position of the tweezer the terminal 45 of the links 4.2will be stopped by the ears 39 of the jaws as shown in Fig. 1. Inassembling, the sides of the channel link 42' may be pressed into thereduced ends 41 of the pivot pins 40'and if desired the freeterminals'of the reduced ends may be upset although in actual practiceit has been found that upsetting is not necessary.

With the present arrangement, there is no possibility of injuring thehand orface of the operator due to pinching when using the tweezer.Heretofore. the link members 42 were reversed and had their channelsfacing upwardly and rearwardly. In Fig. 2, the gap portions shownbetween the ear 39 andterminal 45, formerly appeared between the ear 38and the adjacent wardly, the gap which formerly appeared between the ear38 and the adjacent terminal of the link formed in effect a miniaturetweezer which tended at times to catch the flesh of the user. It hasbeen found that by reversing and inverting the channel links to facedownwardly and forwardly the miniature tweezer is formed by theterminals 45 and ear 39 where it can. do no harm'or injury.

In assembling the tweezer instrument,- the jaws and arms are firstinterconnectedby the channel shaped links. 10 and 11 are placed togetherso that the boss 18 will fit into recess 17 and the shoulders 20 and'21contact. The cylindrical plug; orretainer 29 is placed within the boreof the guide 16. The helicoidal spring then inserted in the guide.Following this, the upper portions of the Subsequently the jaws.

part of the tubular guide.

jaws 10 and 11 are arranged within the lower With the cylindrical plug29 against the top inner face of the squared portion and the springs 30disposed between the plug and the jaw 11 in such fashion as to be underno compression, the upper portions of the arms are below the sockets ofthe guide.

In order that the upper portions of the arms maybe raised to theelevation of the sockets,

spring 30 must be compressed or made shorter.

- the 'tweezer instrument.

With the rod 45 againstthe cylindricalretainer 29the wings of thetweezer are bodily m'ove'd rearwardly against the energy of spring 30.This causes the retainer to move awayfrom the top inner face of thesquared-portion and also aids'to'comp'ress the spring. If the spring becompressed the upper portions of the tweezer arms may be extended tointerlock with the guide. Thus the flanges of the jaws may be brought tothe elevation of the sockets 3-1 in which they are slipped. The tweezerinstrument is then removed from the fixed extension 45 and thusthe'spring 30'automatically.expands. Consequently the cylindrical plugpasses into the curved recesses 34 of the flanges 32 and locks the'latter against transverse slippage. Down- Ward pressure by the spring oncylindricalpart 24 :of jaw 11 causes the hair gripping andextractingportions Hand 13 of the jaws to be normallyv spread apart.

To dismantle the instrument, if assembled, rod 451s. inserted in thebore of the knob 27 to press down the locking plug below the recesses.34 whereupon the'flanges .32 may be slipped outof the sockets31. Thenthe wings slwith linked jaws maybe removed from' the guide, as may alsobe helicoidal spring 30 and the 'iockingplug.

In operation, the wings 22 of the'tweezer may be gripped at 47 betweenthe fingers, preferably the thumb and index finger of thexright'or left'hand'at substantially any angle. Upon compression; that is'upo'n themovement of. the jaws toward each'other, the first step of themovementzof the arms will bring the gripping extracting faces 12 and1301? the jaws together. This position may; be considered as the initialclampinghor gripping position of the tweezer. In this position thegripping and extracting faces are against a hair to be extracted, Toextract a. hair to" whichv the tweezerhas been applied, it isneces'sarythat the jaws be ,moved rearwardly: This stroke is caused on the-secondstep of the-movement of the wings in th'e'directikinttowardsv-eachother. However, it is also essentialthat the initial grip on the hair byfaces 12 and -13'bemaintaine'd or increased during the extracting strokeor" the jaws. For this purpose and to insure that the faces 12 and 13hold the hair without slippage, supplementary pressure is provided onthe sides of the tweezer jaws; Inthe preferred form of the invention,the 'side pressure 'is supplied by'interconnecting the wings and theupper portion of the jaws with suitable helicoidal springs 50. Forexample,

:in'the'form shown'in Figs. 1 and 2, springs 50 are substantiallyhorizontal that is approximately atnine'tydegrees with respect to theaxis of the tubular guide. In the form according to -Fig.=9, pressuresprings i) connected to the jaws andxarms OfltlIGtWEGZEI .areapproximately at spring 30'.

an angle of forty five degrees with the tweezer expanded. In the case ofthe form illustrated Figs. 1 and 2 the outer ends of the springs-50 areremovably mounted on a stud '51 on the inside of the arms or wings andthe inner ends are disconnectably mounted on the shank 52 underneath thehead of a button 53 which bears against the sides of the jaws and isremovably part of the tubular'guide. I

With regard to the springs 50 shown' in Fig. 9 their outer endsareremovably mounted on posts 51 carried by the arms and their innerends are appropriately, in similar fashion, disconnectab'ly disposedwithin an opening as 54 at the lower arranged on studs or posts 55c'arriedby-the jaws.

With the tweeze'r jaws brought merelyto gether such that the grippingand extracting 'faces 12 and 13 initially clamp a hair to be extracted,no effective side pressure is created by the laterally disposed springs50; Upon further manipulation of the-wings efifectiveside pressure isbrought about due to the compression of the springs 50 as the rearwardstroke of the jaws commences and progressively increases until therearward strokeconcludes. It is thus apparent that the grip on the hairby the faces 12 and 13 is intensified due to the gradual inereas'e'" ofcompression of the lateral springs 50 during the extracting stroke ofthe jaws. Hence the grip on a hair by the jaws will be sustained and"consequently preclude slippage of the jaws overthe hair. With the hairfirmly clamped on the rearward stroke, thehair pulls away from the fleshand at the completion of this stroke and the 'tweezer takes the formshown in Fig. 2, namely collapsed. i If the side pressure applied by theoperator be now removed from the actuating surfaces 4'7, the jaws moveforwardly by reason of theactien of spring 30 and consequently separatewithfthe result that the hair forn'i'erlywithdrawnfrom the flesh'isdiscarded. Onthereturn of the jaws to normal the latera1'springs'5i)expand as is the case also of the more powerful helicoidal It has beendiscovered 3 that with the lateral springs "disposed between the jawsand wings, the tweezer'operates in a relatively silent'iash ion doingpractically away withthe objection able 'clicking between the links, theextensions 44, and -.ears 39. The clicking -ac'tionformerly developedwith tweezers of the character referred to which did not utilize sidesprings is now substantially absorbed or cushioned by the compensatingsprings 50.

In the form of the invention accordingito Fig. 8, provision has beenmade for adjusting or regulating the tension of the side springs '50. Tothis end, stud 51 is threaded. and cooperates with a knurled threadeddisc wheel and the latter may be shifted along'the stud to "regulate thespring to the desired pressure;

According to the farm illustrated in Fig. 10, the pressure is applied tothe jaws by the aidof an inverted U shaped flat spring 61 disposed in acorrespondingly shaped groove formedat the upper part of the jaws,thespring 61 having perforated terminals threadably engaging a shank ofa set screw 62. Pressure ofthe sides of the jaws may be-reglil2ttdbadjusting set screws 62.

If desired, the gripping and extracting faces Cir of the jaws. Morespecifically however extending from each disc is a shank '71 which isfreely ping and extracting jaw after a full cycle of the tweezer hasbeen completed, namely after a rearward extracting stroke, the disc towhich the hair is sustained may be rotated and this action separates anddiscards the hair therefrom. Y

In the case of the preferred embodiments illustrated in Figs. 16 to 20inclusive, the cylindrical sleeve or guide and the squared head ormember 81 are made invtwo separate parts. Head 81 includes alongitudinal'channel or bore 82 which receives the helicoidal spring 83,the terminals of which overhang opposite sides of the head and normallyabut the upper portions of the arms or wings 33 of the tweezer, whicharms are appropriately pivotally connected to the upper portion of thehead by suitable pivots 84. Head 81 is provided with an integral andspheroidal shaped terminal 85. From the lower horizontal face 86 of thehead integrally depends the axially arranged cylindrical post 8'7 havinga bottom flat face 88. The lower face 86 of the head 81 is also providedwith opposed detents or small projections 89 for a purpose hereinafterdescribed. The cylindrical, sleeve or guide 80 in which the pivotalconnection formed at the upper end of the jaws l0 and 11 is housedcomprises a shell or casing having a top wall 90 including a concentricopening 91in which the depending post 8'? of the head81 is removablyreceived. The inner face of the sleeve is provided with the opposed andalined guide slots 92 and 93 extending substantially the entire heightvthereof, which-slots guide the reduced terminals ofa pin 94 looselycarried by and at the. lower part of the head 95 of an adjustable studgenerally designated96, the threaded shank 97 of which is threadablyinterconnected in. the threaded bore 98 of the boss or lug 18 at theupper part of jawll, the boss being disposed in a suitable elongatedrecess 17, which in association with cooperating shoulders as'20 and 21of the type described in connection with Figs. 5 provide the pivotaljoint between the jaws 10 and 11. I

A helicoidal vertically disposed spring 99 has its lower end seated onthe overhangingportions of the pin 94 and surrounds'a major portion ofthe head of the stud 96., The upper end of spring 99 surrounds thedepending post or extension 8'7 and abuts the inside face of the topwall 90 of the sleeve. Hence, spring 90 has a double function, to wit,first in urging the top wall of the guide sleeve against the lower faceof the head 81 and secondly in imparting a downward force against thelateral flange 100 overhanging the upper part of the jaw 11 for normallyseparating the lower gripping faces of the jaws.

Since the spring supporting pin 94 is non rotatably guided in thevertical sleeve 80, rotation of the sleeve will accordingly bodily carrythe pin 94 with it. Consequently, if the sleeve be rotated relative tothe post 87 and the pivotally connected jaws, the threaded shank will berotated and thus, either increase or decrease the distance between headof adjustable stud 96 and the bottom part of the post 87,depending uponthe direction of rotation of the sleeve.

As illustrated in Fig. 16, the shank 98 occu pies substantially theentire length of the internally threaded bore 89 of boss '18 and the pin100 which acts as a stop and limits-the downward movement of the head95. In such, position of shank 9B, the vertical spring 99,1 'as1con- Y:15

fined within the sleeve is under leastjcompression. Hence less downwardpressure is transmitted for the separation of the jaws- Itfollowstherefore that less pressure need be 'applied to the jaws for theirseparation. Correspondingly less pressure is necessary .On the part ofthe operator in the manipulating 1 of the wings for retraction of thejaws. In the position of the shank 98 as illustrated in Fig. 16, thedistance between the head 96 thereof and the post 8'? is the equivalentto their largest distance of separation, or equivalent to the longestrearward stroke of the jaws under the least opposing spring pressure bythe helicoidal spring According to the forms of the invention shown inFigs. 16 and 20, links 101 have their ends pivotally connected to theinside of the bottom parts of wings 33 and to suitable lugs 102 carriedby the jaws. If therefore the wings be brought in a direction towardseach other,-the links operate to simultaneously retract both of thejaws. On the completion of the rearward stroke, spring 99 automaticallyoperates when finger pressure is removed from the wings to move the jawsforwardly and apart.

The wings are also normally urged outwardly by reason of spring 83 whichbecame contracted on the movement of the wings towards each other andautomatically expands upon release of finger pressure from the wings. I

With the sleeve and studadjusted'for the longest, rearward stroke of thetweezer, as in Fig. 16, hairs offering little resistance toextracthreaded shank 9'7 with respect to its boss'such that the distancebetween the head of fstud 96 and post 87 is decreased and thuscompressing the helicoidal spring 99. Consequently, added fingerpressure on the wings is necessary on the part of the operator toovercome the increased spring pressure on the jaws. This'extra pressureapplied to the wings overcomes the added resistance to extractionoffered by the hairs and also prevents slippage of the hair between theclamping and extracting faces of the jaws during the latters retraction.In a similar fashion the sleeve and jaws may be adjusted and'set forhairs offering various degrees of resistance for their extraction.

As illustrated in Fig.17, the sleeve has. been rotated as to arrange amajor portion of the 1 0 v 94 is disposed adjacent theoverhangingflange' threaded shank 97 above the overhangingv flangepressed. Therefore there. isv no gap between the head and the.projection 87. .It follows that although the wings 33 may bemanipulatedas to.

bring. the lower portions of the jaws. towards each other to gripa hair.nevertheless it will be impossible to'slidably shift the jaws rearwardlyrelative to the guide sleeve. In .this case, to extract .a hair it isnecessary tohold the jaws together, by finger pressure on the wingsxandmanually move the entire construction of the tweezer bodily rearwardly.in a. direction away from the. hair. In this operation, the tweezer,

if adjusted for no rearward stroke of'the jaws,-

isv similar in operation to the simple plain tweezer of the type wellknown in the art, which consists merely of two. hinged jaws adapted-toextracta hair provided itis bodily. moved away from the hair. I

-;When the wings of the. tweezer according to the forms shown in Figs.16.and.20 inclusive are rapidly manipulated after the stroke.. andpres-fsure. on, the .jaws thereof have ,been adjusted,- .as desired, it hasbeen foundthat this adjustment becomes disturbed unless appropriatemeans is provided to, prevent partial and accumulative: rotation of. the,guide sleeve which otherwise would take;place. =-..'Io ,overcome this;difiicu-lty,;

namely to prevent partial. rotation ortcreepage of the sleeve during themanipulation of the wings, t e top wall-.90 of .thesleeveis provided Inthis case of the embodiment illustrated in,

Fig. 20,;the latter inconstruction; is similar to the-tweezer inaccordancexwith Figs. 16 to 19 inclusive except that the wings and jawsthereof are interconnected by suitable oblique springs as 106 to provideautomatic gradually increasing side pressure tothe jaws .astheirextracting stroke progresses rearwardly.
